bowler

The word 'bowler' is a straightforward agent noun formation from the verb 'to bowl,' which originally meant to roll a ball. The verb 'bowl' itself traces back to the Latin bulla, meaning a bubble or round object, a semantic core perfectly preserved in the spherical balls used in games. The suffix '-er,' of ancient Germanic origin via Latin, is the standard English device for creating nouns indicating a person associated with an action. Therefore, the literal "one who bowls" first applied to players in games like cricket and lawn bowls. By the late 19th century, the term was humorously transferred to the distinctive, rounded, hard felt hat, likely because its shape resembled a bowl or because it was worn by sporting gentlemen.
